[RESOLVED] How can I implement bidirectional communication between two processes?

[vincegata]

Hello,

I have two command line apps, one of them is multithreaded. I need to implement a bidirectional communication between them. Currently I can do

ProgramA 1> ProgramB

for the first programA to direct output into ProgramB, however I also need ProgramB to send messages to ProgramA.

Can you give me ideas, maybe samples, how to implement it in a easiest way. Thank you!

btw, I am on Ubuntu.

EDIT: I'd rather not to use third party libraries, Boost, etc.
